[The diagnosis of cyclosporin nephrotoxicity in patients after kidney transplantation].

The authors review possibilities of thin needle aspiration biopsy of renal allotransplants in the diagnosis of cyclosporin nephrotoxicity. 151 thin needle aspiration biopsy specimens were explored in 55 patients following kidney transplantation. According to the authors, this method when applied in the early postoperative period may turn an informative one. However, if the time elapsed after operation exceeds 3 months, they recommend performing puncture biopsy of renal transplants.
